Installing Cables
1. The power cables and signal cables should be tied and cased separately.
2. The shielding layer of signal cable must be grounded.
3. In underfloor cabling, if it is hard to bend the cable 90°, disassemble the cable and fix it using
the pipe clamp. As the PE cable is long, prepare the five-core cable based on the length of the
PE cable.
4. The recommended upstream switch is C63 or higher.
5. The outdoor unit, indoor unit and Water Cooling Module must receive power from the indoor
unit.
